Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Jacqueline N. Hewitt, Kai-Feng Chen, Honggeun Kim, Joshua S. Dillon | Summary: Motivated by the desire for wide-field images with well-defined statistical properties for 21cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator for the sky using the interferometric […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Zarif Kader, Calvin Leung, Matt Dobbs, Kiyoshi W. Masui, Daniele Michilli | Summary: The gravitational field of compact objects, such as primordial black holes, can create multiple images of background sources. For transients such as fast radio bursts (FRBs), these multiple images can be resolved in […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Halston Lim, Gaurav Khanna, Scott A. Hughes, , | Summary: In recent work, we examined how different modes in the ringdown phase of a binary coalescence are excited as a function of the final plunge geometry. At least in the large mass ratio limit, we found […]

Kavli Affiliate: Avi Shporer | First 5 Authors: Adriana Errico, Robert A. Wittenmyer, Jonathan Horner, Zhexing Li, Gregory Mirek Brandt | Summary: We report the discovery of a highly eccentric long-period Jovian planet orbiting the hot-Jupiter host HD,83443. By combining radial velocity data from four instruments (AAT/UCLES, Keck/HIRES, HARPS, Minerva-Australis) spanning more than two decades, […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Wenju Zhang, Xiang Zhang, Qing Liao, Long Lan, Mengzhu Wang | Summary: Nuclear norm maximization has shown the power to enhance the transferability of unsupervised domain adaptation model (UDA) in an empirical scheme. In this paper, we identify a new property termed equity, which indicates the balance […]
Kavli Affiliate: Daniel Holz | First 5 Authors: Pierre Auclair, David Bacon, Tessa Baker, Tiago Barreiro, Nicola Bartolo | Summary: The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and particle […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ann Rutt, Jimmy-Xuan Shen, Matthew Horton, Jiyoon Kim, Jerry Lin | Summary: Multivalent batteries are an energy storage technology with the potential to surpass lithium-ion batteries, however their performance has been limited by the low voltages and poor solid-state ionic mobility of available cathodes. A computational […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I explore the properties of "dark gaps" – regions in quasar absorption spectra without significant transmission – with several simulations from the Cosmic Reionization On Computers (CROC) project. CROC simulations in largest available boxes (120 cMpc) come close […]
